Experimental study of differential pressure transducers

The factors having influence on the performance of certain type of differential pressure transducer used in Dayawan Nuclear Plant are researched and analyzed in this paper. From the view of installation angle, environment temperature, static pressure and fluid temperature, the simulation experiment is designed, which is help of finding out the key factors . Experimental results show that the actual working performance of the transducers can’t meet the requirements of measuring accuracy , and new type of differential pressure transducers with better performance is selected to solve the problem once and finally. The type-selection method of transducers is given too.
